Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74980, here are decompositions:
- 47 + 74933 = 74980
- 83 + 74897 = 74980
- 89 + 74891 = 74980
- 107 + 74873 = 74980
- 137 + 74843 = 74980
- 149 + 74831 = 74980
- 233 + 74747 = 74980
- 251 + 74729 = 74980
Showing the first eight; more decompositions exist.
